This, of course, is not optimal and you wouldn't use it for production.

In production you would have one of the options above.

But it's the simplest way to focus on the server-side of WebSockets and have a working example:

```Python hl_lines="2  6-38  41-43"
{!../../../docs_src/websockets/tutorial001.py!}
```

## Create a `websocket`

In your **FastAPI** application, create a `websocket`:

  feedback for that case. However, when offline mode is declared, nothing
  earmarked as remote should be accessed, regardless of whether it is actually
  a physically local resource.

  NOTE: One side-effect of this design change is that all offline-mode code can
  be isolated to maven-core, maven-plugin-descriptor, and [possibly]
  maven-artifact. Usage of maven-wagon will be determined by an offline-aware
  manager.

Você terá completação do seu código que você poderia considerar impossível antes. Como por exemplo, a chave `price` dentro do corpo JSON (que poderia ter sido aninhado) que vem de uma requisição.

Sem a necessidade de digitar nomes de chaves erroneamente, ir e voltar entre documentações, ou rolar pela página para descobrir se você utilizou `username` or `user_name`.

### Breve

On the other side, there are thousands of users in the chat systems, so there's a high chance you'll find someone to talk to there, almost all the time. 😄

  5. Combined Libraries.

  You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:

  - true/strict - perform validation and error the request on any invalid fields in the ojbect. It will attempt to perform server-side validation if it is enabled on the apiserver, otherwise it will fall back to client-side validation.

        default in tf 2.8, and the behavior change will likely to cause some
        breakage on user side (eg if the test is checking against some golden
        number). These 3 APIs will allow user to disable and switch back to
        legacy behavior if they prefer. In future (eg TF 2.10), we expect to

conta desse código ser executado antes da aplicação **começar** a receber requisições, e logo após **terminar** de lidar com as requisições, ele cobre toda a **vida útil** (_lifespan_) da aplicação (o termo "vida útil" será importante em um segundo 😉).

Pode ser muito útil para configurar **recursos** que você precisa usar por toda aplicação, e que são **compartilhados** entre as requisições, e/ou que você precisa **limpar** depois. Por exemplo, o pool de uma conexão com o banco de dados ou...
